NATHANIEL ALLEN HARRIS, OF ATHLONE, NORTH CAROLINA, ASSIGNOR OF ONE-HALF TO LOWRIE D. CORY, OF PALISADES, NEW YORK.

WOOD FILLER AND STAIN AND PROCESS OF MAKING SAME.

No Drawing.

To all whom it may concern Be it known that I, NATHANIEL ALLEN HARRIS, a citizen of the United States, residing in Athlone, in the county of Yancey and State of North Carolina, have invented certain new and useful Improvements in Wood Fillers and Stains and Processes of Making Same, of which the following is a specification. I

The object of this invention is to provide an e'liicient wood stain for different kinds of wood which will at the same time act as a filler for the wood whether the latter be soft or hard.

In carrying out my invention I proceed as follows: I take the thick, heavy outside bark of the spruce pine tree commonly found in the mountains of North Carolina and known as Tsuga canadens'z's and Tsuga Oarolz'm'ana. I communicate the bark of either of these trees preferably by pounding it into small pieces. The bark thus reduced in size is covered with cold water and then boiled until the contained resin is extracted. The resin-containing-liquid thus produced is next strained through a fine cloth either while hot or when cold. To every three gallons of this liquid I add about one-fourth pound of lye or potash preferably of the kind known as red seal lye or potash now commonly found on the market. The lye or potash has the effect of making the resin take or permeate the wood and produce the desired filler and finish and when dry to present a smooth hard surface to which additional layers of the stain or layers of oil may be applied. After the resinous liquid and the lye or potash are mixed ner above specified, they are allowed to cool and may then be applied to the wood by a brush in the usual way. Generally the first coating will dry in an hour and successive coatings of the combined filler and stain may be added, or one or more coats of oil may be applied. One application will produce a cherry finish and successive applica- Specification of Letters Patent. Application filed March 26, 1914.

tions will give different shades of red, While applications of oil will produce a brilliant glossy finish and no further treatment is reuired.

q The combined filler and stain can be used with equal success on hard and's'oft woods.

I would call attention to the fact that I use only the thick heavy outside bark of the spruce pine tree above referred to, as the inside bark is not so good.

I claim as my invention:

1.. The process herein described of making a combined filler and stain for hard and soft woods which consists in comminuting the outer bark of the spruce pine tree (Tsuga camadensz's or Tsuga Ortrolz'm'ana), mixing it with water,'boiling this mixture, straining it and adding thereto lye or potash in the proportions of about three gallons of the resinous liquid to about one-fourth pound of lye.

2. The process herein described of making a combined filler and stain for hard and soft woods, which consists in comminuting the outer bark of the spruce pine treev (Tsuga canadensz's or Tsuga OaroZz'nz'ana), mixing it with water, boiling this mixture, straining it and adding thereto ordinary commercial red seal lye or potash in the proportions of about three gallons of the resinous liquid to about one-fourth pound of lye.

3. The combined filler and stain for hard and soft woods herein described, consisting of a resinous liquid extracted from the outer bark. of the spruce pine tree. (Tsuga canadensz's or Tsuga Oarolz'm'ana), and lye or potash in the proportions of about three gallons of the resinous liquid to about onefourth pound of lye.

In testimony whereof, I have hereunto subscribed my name.

his NATHANIEL X ALLEN HARRIS.
